George Thorogood is still bad to the bone. The longtime rocker played his first gig four decades ago, but he and his Delaware Destroyers aren't showing signs of slowing down. Thorogood has no problem with playing the hits, and there's little doubt that he'll be dusting off classics such as "Bad to the Bone," "I Drink Alone," "One Bourbon, One Scotch, One Beer" and "Move It On Over" when he comes to town for a free concert this week. The show, part of the state's Summer at the Plaza series, also features local rockers Scotty Mac & the Rockin' Bonnevilles and Kentucky-based rock act Fifth on the Floor. 5 p.m. Wednesday. Free. Empire State Plaza, Albany. 473-1845; http://www.summer.empirestateplaza.org
